Attention! When searching for leaks, avoid personal contact with R134a refrigerant.
Leak detection using a leak detection device should be carried out in accordance with the operating instructions of the device manufacturer. If a R134a refrigerant leak is detected during the filling of the air conditioner, it is necessary to fill the air conditioner in spite of this. Then search for leaks using the device.
The search for leaks should be carried out in the absence of ventilation of units and pipelines, because air currents carry away the escaping R134a refrigerant, preventing the device from fixing the place of their occurrence. Mark the detected leaks, pump out the R134a refrigerant and seal the pipeline (node) or replace them. After fixing the leak, fill the system with R134a refrigerant and repeat the leak search.
